evilunicorncatI would imagine the YUMIs and YU5s would sound better overall but if placing close to a wall you're gonna get pretty bad boundary boost (?) from the rear port.
The Edifiers, from what I've heard, are very good sounding speakers but may not be quite as accurate as the Kanto alternatives. They're front ported, however, so if you place them close to a wall they'll still sound good. Hope this helps!
